I don’t gym. I lift things that need to be lifted. Last week or so I lifted an a-frame I built (one side with 2 legs) and while loving it around the shop, didn’t move my feet and twisted my torso to go toward the door. Fucking mistake. I’m methodical and calculated about my movement because of things like this, but was not paying attention, was worn out, fuck me. Took a few days to get back to normal. Back to the a-frame. Didn’t want to call anyone to help out my mantel in place. It’s 10ft long, 8”x13” live edge old growth river claimed cypress (think that river logger show from years back) So I built an a-frame with 2x6 legs. Double 2x12 ridge beam. Cross braces, 2 x 8:1 hoists to lift it into place. Mantel was back cut for 4 - 2x4’s I had coming out of the wall (back braced into the fireplace framing with cripples below and above to the header, nailed and screwed, so the 2x4 that cantilever out can’t tilt up in the back. It went in like fucking butter. Just had to belt sand one bottom of a 2x4 as it was a little larger than my test board. Use levers. Use male conical advantage. Use White people things at every turn. Get better bro.
